In 1963 Horst Brüning set up an architecture and design office in Stuttgart. During this period, Brüning came in contact with Kill International and the architect duo Fabricius & Kastholm, involving a successful exchange of ideas, which in the end led to international recognition and success. It was in this periode the HB 6917 was designed. Brüning and Fabricius & Kastholm’s designs were originally manufactured by the same company, and have today been resumed by Lange Production to continue this original idea.
